Константа Джанго вызывает ошибку транзакции

0 голосов
/ 01 ноября 2018

Я использую django 1.11, администратор может настроить, должны ли пароли быть сложными или нет, поэтому я использовал constace, чтобы включить эту конфигурацию.

settings.py 

AUTH_PASSWORD_VALIDATORS = [
{
    'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
},
{
    'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
    'OPTIONS': {
        'min_length': 8,
    }
},
{
    'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
},
{
     'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
},
{'NAME': 'apps.core.password_validators.NumberValidator', },
# {'NAME': '.apps.core.password_validators.UppercaseValidator', },
# {'NAME': '.apps.core.password_validators.LowercaseValidator', },
# {'NAME': '.apps.core.password_validators.SymbolValidator', }
]

CONSTANCE_CONFIG = {
'PASSWORD_LIFETIME': (365*25, _('The time in Days how long a Password is valid'), int),
'PASSWORD_COMPLEXITY': (True, _('When set to true the Password must contain symbols, numbers, and upper/lowercase letters.')),
'SESSION_COOKIE_AGE': (14*24*60, _('The time in minutes how long a session is valid'), int),
}

password_validation.py: из константы импорт конфиг 

class NumberValidator(object):
def validate(self, password, user=None):
    is_complex = bool(config.PASSWORD_COMPLEXITY)

    if is_complex:
        if not re.findall('\d', password):
            raise ValidationError(
                _("The password must contain at least 1 digit, 0-9."),
                code='password_no_number',
            )

def get_help_text(self):
    if config.PASSWORD_COMPLEXITY:
        return _(
            "Your password must contain at least 1 digit, 0-9."
        )
    else:
        return ''

При создании нового пользователя через интерфейс администратора я получаю следующее:

текущая транзакция прервана, команды игнорируются до конца блока транзакции

Код работает, когда я удаляю часть config.PASSWORD_COMPLEXITY.

Есть идеи, почему использование константы вызывает такой тип ошибки?

Решение проблемы заключается в следующем: Я пропустил добавление приложения «constance.backends.database» в настройку установленных приложений django.

Ошибка найти сложно. Ключ должен был проверить журналы postgres, которые показали, что таблица для константы не существует.
